Question

max built a skateboard ramp that is 16 inches high. the angle formed by the ramp and the ground is 21 degrees. what is the length of the ramp?

Answer 1

The length of the ramp can be found using the tangent function:

tan(21°) = height/length

length = height / tan(21°)

length = 16 inches / tan(21°)

Note: make sure to convert the height from inches to the same unit used in the tangent function, usually radians.
